{"version":"1.0","type":"rich","title":"Blank Canvas","description":"A blank, rounded rectangle fills the entire browser viewport as the sole visual element. The piece demonstrates a minimalist SVG canvas setup using D3 v5, where the `d3.select` method targets the empty `<svg>` element and sets its dimensions to match the viewport's client width and height. A single `rect` is appended with a 40-pixel corner radius, creating a simple framed shape against the white background. The fixed-position CSS ensures the canvas remains stable within the browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c127cb68045b43e28bb1ee06fa795030?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
